Short answer: Maybe not. Honey is one of the most commonly counterfeited foods in the world, and regulators have found adulteration in up to 46% of tested import samples. Home tests (water, thumb, flame, ants) can’t catch modern fraud, and only specialist lab methods like isotope-ratio analysis and NMR can confirm a honey is unadulterated. Since you can’t run those on your own jar, the practical approach is to check four things on any honey you buy: a named source, a published independent lab report, what that report actually tests, and whether the honey is single-source rather than blended. This guide shows how to check each one.

This article covers what to check on any honey, and what lab tests can and can’t prove.

How big is the honey fraud problem, really?

This isn’t a fringe concern — it’s one of the most investigated categories of food fraud globally, and the numbers are well documented by regulators, not brand marketing:

• The European Commission’s Joint Research Centre tested 320 honey shipments imported from 20 countries in 2021–2022 and found 46% suspicious for adulteration — meaning they appeared to violate the EU’s rule that honey should contain nothing but honey.
• The U.S. FDA’s own testing of imported honey for economically motivated adulteration found roughly 10% of samples violative for undeclared added sweeteners in its most recent published assignment.
• A 2018 study published in Food Chemistry found that up to 76% of honey samples from major US retailers had been ultra-filtered — a process that strips out the pollen that would otherwise let researchers trace where the honey actually came from.
• Honey fraud is widely cited by food-safety researchers as one of the three most commonly counterfeited food products in the world, alongside olive oil and fish.

None of this means every jar on a store shelf is fake. It means “raw,” “pure,” and “natural” on a label are marketing terms, not verified claims — and the gap between the two is where the fraud lives.

How honey actually gets faked

Honey fraud isn’t usually about substituting something else entirely — it’s about stretching real honey with something cheaper and hiding it well enough to pass basic testing. The two dominant methods:

Sugar-syrup dilution. Cheap syrups — corn, rice, wheat, or sugar beet — are blended into real honey to increase volume at a fraction of the cost. Older detection methods looked for corn and cane sugar specifically; as those got easier to catch, some producers reportedly shifted to rice and beet syrups, which older lab methods struggled to flag. This is why modern testing increasingly relies on Nuclear Magnetic Resonance (NMR) analysis rather than older sugar-panel tests.

Ultra-filtration. Heating and filtering honey until the pollen is removed doesn’t add anything fraudulent by itself, but it erases the one thing that would let a lab trace the honey’s true geographic and botanical origin — which is exactly the point. It also typically means the honey has been heated well past what “raw” implies, degrading enzymes and aroma compounds in the process.

Both tactics are built to slip past a glance at the label and a basic sugar test. Modern lab testing makes them much harder to hide.

Why you can’t reliably tell by taste, color, or texture

Search around, and you’ll find popular home tests — the water test (does it dissolve or sink), the thumb test (does it stay put on your skin), the flame test (does it ignite), the ant test (do ants avoid it). None of these are validated by food-science research as reliable fraud detection. Adulterated honey can pass all of them because sophisticated blends are engineered to mimic real honey’s viscosity, color, and behavior—and the ant test fails on basic logic: ants are generally drawn to sugar, and real honey is full of natural sugar. These tests can catch the most obvious, cheapest fakes; they cannot catch a rice-syrup blend calibrated to fool a thumb test.

The flame test, in particular, is worth avoiding for a second reason beyond unreliability: it requires holding an open flame to a food item, which is a real hazard for a test that doesn’t even work.

One home observation does carry some signal, with a caveat: raw honey typically crystallizes over time, while heavily processed honey often stays liquid indefinitely. It’s a useful supporting clue, not a stand-alone test — some genuine raw honeys stay liquid longer depending on floral source (buckwheat crystallizes differently than wildflower, for instance), so treat it as one data point, not proof either way.

Lab testing falls into two different families, and it’s worth keeping them apart because they answer different questions.

Authenticity tests — “Is this honey what it claims to be?” These are the methods food-safety regulators and specialist labs use to catch adulteration and heat damage:

• Isotope-ratio mass spectrometry (C4 sugar testing) — detects sugar from corn or sugarcane (C4 plants), which behaves differently from the nectar sugars in real honey.
• NMR (Nuclear Magnetic Resonance) profiling — compares a sample’s full molecular fingerprint against a database of authentic honey, catching adulterants that older sugar-panel tests miss.
• HMF (hydroxymethylfurfural) testing — HMF forms when honey is heated or aged. A low HMF reading is evidence honey wasn’t processed with significant heat, which is a more objective “raw” indicator than the label claim alone.
• Sugar-profile chromatography — separates and quantifies honey’s natural sugars, revealing added syrups that a simple taste test can’t detect.
• Enzyme activity testing — measures diastase and invertase, enzymes bees themselves add to honey. Low activity can indicate the honey was over-processed or diluted.
• Water content (refractometer) — pure honey runs below roughly 18% moisture; high water content points to premature harvesting or adulteration.
• Pollen analysis (melissopalynology) — examines residual pollen to verify floral source and geographic origin, which is exactly what ultra-filtration is designed to erase.

Contaminant tests — “What shouldn’t be in this honey?” These screen for residues rather than for dilution:

• Antibiotic and veterinary-drug screening — checks whether the bees were treated with antibiotics, which can leave residues in honey.
• Pesticide and herbicide screening, including glyphosate — checks for residues from treated fields or contaminated nectar sources.

A clean result on a contaminant test is genuinely useful, but it says nothing about whether the honey was stretched with syrup. Only the authenticity tests above can speak to that.

How to read a Certificate of Analysis (COA)

A COA is only as informative as the tests it contains, so the first thing to check is which tests were run. Here is how to read the common ones:

The first two rows are contaminant screens. The last two are authenticity tests. A COA can contain one family without the other, and a clean contaminant screen does not prove the honey is unadulterated.

How to read “Not Detected,” “<MDL,” and “<MQL.” Labs report a clean result in different ways. Not Detected means no signal was found. <MDL means the amount is below the method detection limit, the smallest amount the method can reliably tell apart from background noise. <MQL (sometimes LOQ) means it is below the method quantification limit, the smallest amount that can be measured with confidence. All three are generally accepted as clean results. None of them means “zero”: they mean “below what this method can reliably see.” That is why the lab, the method and the reporting limit matter as much as the word on the page.

A brand that shows you which tests it ran, names the accredited lab and method, and publishes the report is giving you something a marketing claim never can: a checkable claim. A brand that publishes only contaminant screens is giving you real information, but about a different question than “is this honey adulterated?”

A real example: reading an actual COA (and what it doesn’t show)

OneRoot Honey’s Organic Wildflower was tested by an independent lab (Submission #25-096810, sampled Oct. 30, 2025, reported Nov. 21, 2025). The report covers two screens:

• Non-sulfa antibiotics and veterinary drugs (nine compounds): chloramphenicol, chlortetracycline, erythromycin, fumagillin, lincomycin, oxytetracycline, penicillin G, tetracycline and tylosin. All Not Detected.
• Polar pesticide screens A and B (35 compounds): including glyphosate, its breakdown product AMPA, glufosinate, paraquat, diquat and chlormequat. All Not Detected.

That is a meaningful result for anyone concerned about drug and herbicide residues. It is also worth being clear about what this report is not: it is a residue screen, not an authenticity panel. It does not include HMF, isotope-ratio or NMR results.

What OneRoot offers, which most do not, on the question of dilution is source traceability rather than a lab result: single-source honey from OneRoot comes from one apiary and one harvest, so there is no blending step where syrup or other honey could be mixed in. That is a built-in structural safeguard to ensure the product is 100% pure honey.

Your checklist: what to check on any honey

• Does the brand name a specific country or region of origin — not just “Product of USA/Canada” (which can legally apply to honey that was only bottled there)?
• Do they publish actual lab results, or just claim to be “raw” and “pure”? And if they do, which tests does the report cover: contaminants, authenticity, or both?
• Is the honey single-source, or blended from multiple countries?
• Does the label list anything other than honey?
• Is the price realistic? Genuine raw honey typically costs meaningfully more per pound than store-brand honey — a price far below that is a signal, not a bargain.

Where OneRoot fits

OneRoot’s honey is single-source and independently tested for drug and herbicide residues, and the 3kg Wildflower and Buckwheat sizes are the best value at the lowest price per jar. The certified-organic line is a genuine upgrade for buyers who specifically want independently audited pesticide-free foraging on top of that — a premium option, not a requirement for a trustworthy jar.

Bottom line

You can’t detect modern honey fraud with a glass of water or a lit match — it takes lab testing that most brands never do and even fewer publish. The fastest way to buy with confidence is to buy from producers who name their source, publish independent lab reports, and are clear about what those reports do and don’t cover, not just the word “raw” on the front of the jar.

FAQ

Is most honey on grocery shelves fake?

Not necessarily fake outright, but a meaningful share is adulterated with cheap sugar syrups or ultra-filtered to hide its origin. EU testing found 46% of imported honey samples suspicious for adulteration; FDA testing found roughly 10% of imported samples violative for undeclared sweeteners.

Can I tell if honey is fake by doing a water or thumb test at home?

No. These popular home tests aren’t validated by food-safety research and can be passed by sophisticated adulterated blends. Reliable detection requires specialist lab methods like NMR or isotope-ratio testing.

What does HMF measure, and why does it matter?

HMF (hydroxymethylfurfural) is a compound that forms when honey is heated. A low HMF result is evidence the honey wasn’t heavily heated, a more objective “raw” indicator than the label claim alone. HMF also rises with age and storage, so it is an indicator rather than proof.

Does “Product of Canada” or “Product of USA” guarantee the honey wasn’t imported?

No — that label can sometimes apply to honey that was only packaged or bottled domestically, not necessarily harvested there. Look for brands that name the specific region or apiary, not just the bottling country.

What’s the difference between raw honey and organic honey?

“Raw” refers to processing — honey that hasn’t been heated or ultra-filtered. “Organic” refers to certification standards around the bees’ environment, forage, and hive management. A honey can be one, both, or neither; they’re not interchangeable claims.

Does the ant test work — will ants avoid fake honey?

No. This is a myth. Ants are attracted to sugar in general, and real honey is high in natural sugar, so ants will go after genuine and adulterated honey alike.

Does crystallized honey mean it’s real?

Crystallization is a supporting clue, not a definitive test. Raw honey tends to crystallize over time, while heavily processed honey often stays liquid indefinitely — but floral source affects crystallization speed too, so a liquid honey isn’t automatically fake, and a crystallized one isn’t automatically real.
